To all whom it may concern.:

Be it known. that I, PAUL I-I.- SMITH, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented a certain new and useful Improvement in Measuring-Faucets, ofwhich the following is a specication.

The chief object of this invention is to provide a check upon personsdrawing or serving small quantities of liquid from a container and toprevent waste and loss due to carelessness or dishonesty in handling theliquid.

The invention consists, generally stated, in an improved combinationincluding a valved faucet through which only a single unit,approximately, of a liquid can be withdrawn from the container by asingle operation of the valve, and a registering mechanism, operated bythe valve, for registering and indicating the number of times the valvehas been operated, as for withdrawing a unit of the liquid. y

In the accompanying drawing forming part hereof illustrating anembodiment of the invention, Figure 1 is a front view in elevation ofthe invention with a part in section and parts broken out showing itsapplication to a barrel. Fig. 2 is a view in side elevation with theshield for the operating mechanism removed, an outline of the shieldbeing indicated in broken lines. Fig. 3 is a top plan view. Fig. 4: is asection of sufficient parts to showthe liquid passages in the valve andfaucet body.

The faucet body is shown in a form for use in connection with a barrelor keg and comprises a portion 5 for entering the barrel, a nozzle oroutlet 5a and a lateral neck 5b' for the connection of the measuringdevice 6. The valve 7, which is of the plug rotary form has an angularpassage 7 a bored to admit liquid from the barrel into the measuringdevice when standing in a given position or to permit liquid todischarge from the measuring device 6 through the nozzle when turned toanother, the passage in the intermediate position being closed. Intheparticular construction shown the handle 7U of the valve is arrangedon the valve so that it is vertically dependent when the passage 'Y'a isin full open position to admit liquid from the container into themeasuring device and a half revolution of the handle will bring the saidpassage into position to discharge the liquid. Fixed on the stem orshank of the valve adjacent the faucet body is a ratchet wheel 8 engagedby a hook pawl 9 pivoted on the faucet body in position to prevent thehandle 7b from being turned backward. Mounted on the faucet body'vertically above the axis of the valve is a registering mechanism 10 ofany suitable well known construction and having a spring actuated shaft10 provided with an arm 10b and a lug 10G. Fixed on the shank or stem ofthe valve is an arm 7 that revolves with the handle 7b; and the lug 10cstands in the path of the arm 7 so that each time the arm is revolvedthe register arm 1()b is raised by the arm 7c and then retracted by itsspring to normal position. The ratchet, its pawl, the arm 7 C and arm10b and its lug are inclosed in a hood or shield 11 so that there can beno unauthorized manipulation of those parts. The parts are designed tobe so arranged with reference to the passage in the valve so that whenthe handle is raised and revolved the measuring device is filled andthen the register operated before the passage is turned into position todischarge through the nozzle, the contents of the measuring device. Theregister contains suitable exposed number wheels as at 12 to indicatethe total number of complete revolutions of the operating handle so thatit can be readily observed whether the accounting in cash or otherwisecorresponds with that expected or required.

13 is a vent tube connected with the measuring device open at its upperend at or above the level of the liquid in the container so as to permitthe filling and discharge of the measuring device. This tube can be ofsuch small diameter as not to seriously affect the measuring function ofthe measuring device by change in the level of the liquid inthecontainer and the error caused by such change can be corrected orlessened by making the exact quantity to be measured half lill the venttube or by keeping the level of the container constant from a secondcontainer as well understood.

What I claim is:

A measuring faucet comprising, in combination, a measuring deviceprovided with a vent, a faucet body having an inlet and a dischargepassage, with valve chamber between them, a. rotary valve in saidchamber, said valve having an axial passage permanently communicatingwith the measuring device and said valve also having a radial passageconnected With said axial passage and adapted to be moved to directiiuid through the aforesaid inlet passage into the measuring device orfrom the measuring device into the aforesaid discharge passage, aAregistering mechanism including an arm7 an arm in connection With therotary valve for actuating the arm of the registering mechanism andmeans for preventing the PAUL H.
